Hi guys, looking for some help with the wiring behind the dash on a 911 3.2 Carrera. My customer has fitted a new loom behind the dash and repaired the instrument wiring. I’ve managed to sort out the fuse box wiring connections and corrected the wiring to the clocks/Speedo etc. I am having a problem getting the wipers and indicators to work. The hazards work when activated but the indicators won’t do anything. I have wiring diagrams but can’t seem to indentify 4 wires. They are located up by the cigar lighter wiring behind the dash panel. The wires are red/black, black/blue, brown and grey/Green. Any help would be greatly appreciated. I also have a relay 911 618 102 01 which I can’t find a location for. Thanks in advance for any help

I just finished installing a factory tow package on my 2009 Cayenne. When I hook up to a trailer and test, everything works except for brake lights. I checked for power at pins 3&9 on the 7-pin and only have power present there with blinker and not brakes. I've check all fuses related to the tow package (1,3,5,19,&41) and all are good. I tested the trailer on another vehicle and the brake lights work. Since I don't have power to those pins, the issue has to be with the Cayenne. Do I need to have the computer flashed if I am not using electric brakes? The trailer I will be hooking up to has surge brakes, so I didn't think I needed to visit the dealer.
Any assist would be greatly appreciated!!!
Not sure if it makes a difference, but when I purchased this car, it had a Curt hitch with a flat blade connector in the back compartment. I didn't trace out and remove this wiring, only the hitch.
Thanks

Hi - I am looking for some help. The headlights are the litronic ones.

I don't drive the car very often - maybe once a month and often this is in the daylight.

I had a headlight globe 'fail' about 12 months ago. I replaced it and everything seemed good. Then it stopped working. Then it started working. Then both headlights stopped working - some of the time. I am beginning to think that this is possibly not a globe problem.
